Description

Technical Field

[0001] This utility model relates to the field of range hood technology, specifically to a fan cabinet assembly and a range hood. Background Technology

[0002] As people's living standards improve, their demands for a better kitchen cooking environment are also increasing. Range hoods have become an indispensable kitchen appliance in modern homes. Range hoods work by creating a negative pressure zone near the air inlet using a fan assembly, drawing cooking fumes into the fan housing and expelling them outdoors. After a period of use, bacteria may grow inside the fan housing of the range hood.

[0003] Most existing range hoods have germicidal lamps installed inside the fan cabinet to disinfect the components and air inside. To improve the utilization rate of the germicidal light, reflective materials are usually coated on the inner wall of the fan cabinet. However, reflective materials can only achieve diffuse reflection in one direction, and the light energy is greatly attenuated after multiple reflections, resulting in a decrease in the sterilization effect. In addition, there are many blind spots, and the light cannot cover the corner areas. At the same time, in order to ensure the sterilization effect, the germicidal lamps need to operate at high power for a long time, which leads to high energy consumption and accelerated lamp aging.

[0004] Currently, the above problems are usually solved by "improving coverage with a multi-lamp array layout" and "using a rotatable reflector to dynamically adjust the illumination direction". However, the "improving coverage with a multi-lamp array layout" method does not improve the light reflection efficiency, and multiple lamps consume more energy and are more complicated to install; the "using a rotatable reflector to dynamically adjust the illumination direction" method has a complex structure and is expensive. Utility Model Content

[0005] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a blower assembly is provided, the technical solution of which is as follows.

[0006] The air handling unit includes a cabinet and a germicidal lamp assembly. The cabinet encloses a cavity, and the germicidal lamp assembly is connected to the cabinet. The cabinet has an inner wall surface, and the light emitted by the germicidal lamp assembly is at least partially directed toward the inner wall surface. At least a portion of the inner wall surface is provided with a reflective structure, which is configured to reflect the light irradiated onto the inner wall surface.

[0007] The air handling unit of this invention has a reflective structure on its inner wall surface. The light emitted by the germicidal lamp assembly can be reflected by the reflective structure, and the reflected light can sterilize the components located in the accommodating cavity. This not only improves the light reflection efficiency and eliminates blind spots, but also ensures the sterilization effect. It also reduces the dependence on the number and power of the lamps in the germicidal lamp assembly, and extends the service life of the germicidal lamp assembly. At the same time, the structure is simple, reducing energy consumption and maintenance costs.

[0008] For example, a fan assembly is disposed within the accommodating cavity, and the light reflected by the reflective structure has a reflection path, with the fan assembly located on the reflection path. In this way, the light reflected by the reflective structure can sterilize the fan assembly.

[0009] For example, the fan assembly has a volute with an air inlet and an inner wall surface with a corresponding wall surface opposite the air inlet. A reflective structure is disposed on the corresponding wall surface. In this way, light reflected by the reflective structure can sterilize the inside of the volute and the components inside the volute through the air inlet, further eliminating blind spots in irradiation.

[0010] For example, the cabinet has a top panel and side panels. The germicidal lamp assembly is mounted on the top panel, and the reflective structure is mounted on the inner wall of the side panel. In this way, with the germicidal lamp assembly mounted on the top panel, the light shines from top to bottom. When the light shines on the inner wall, the reflective structure can reflect the light to the fan assembly to a great extent, thereby sterilizing the fan assembly, eliminating blind spots in the illumination, and improving the utilization rate of light.

[0011] For example, the side panel includes a front side panel, a rear side panel, a left side panel, and a right side panel, and a reflective structure is provided on the inner wall surface of at least one of the front side panel, rear side panel, left side panel, and right side panel. This improves light reflection efficiency, eliminates blind spots, increases light utilization, and simultaneously simplifies the structure and reduces maintenance costs.

[0012] For example, an uneven structure is formed on the inner wall surface by pressing, and this uneven structure forms a reflective structure. In this way, the uneven structure not only increases the reflective area, allowing the germicidal lamp assembly to achieve sterilization even when operating at lower power, but also reflects the light irradiated onto the inner wall surface in different directions, making full use of every beam of light emitted by the germicidal lamp assembly, eliminating blind spots, improving light utilization, and facilitating the fabrication of the reflective structure, thus reducing maintenance costs.

[0013] For example, the uneven structure is prism-shaped. In this way, the uneven structure can reflect the light that shines on the inner wall surface in different directions, making full use of every beam of light emitted by the germicidal lamp assembly and eliminating blind spots in illumination.

[0014] For example, the uneven structure has a parabolic reflective surface. In this way, the uneven structure can reflect and focus light, thereby enhancing the bactericidal effect of the reflected light.

[0015] For example, the uneven structure has an elliptical reflective surface. In this way, the uneven structure can reflect and focus light, thereby enhancing the bactericidal effect of the reflected light.

[0016] For example, a reflective film layer is provided on the inner wall surface, forming a reflective structure. This effectively improves the light reflection efficiency, eliminates blind spots in irradiation, ensures sterilization effect, reduces dependence on the number and power of lamps in the germicidal lamp assembly, and extends the service life of the germicidal lamp assembly.

[0017] For example, the reflective film is at least one of an aluminum film, a mirror film, or a silicon dioxide coating. In this way, the light reflection efficiency is effectively guaranteed.

[0018] According to another aspect of this utility model, a range hood is provided, including a smoke collection assembly and a fan housing assembly as described above, wherein the smoke collection assembly is connected to the lower part of the fan housing assembly. Since the fan housing assembly described above has the aforementioned beneficial effects, the range hood including the fan housing assembly described above also has the aforementioned beneficial effects, which will not be elaborated further here.

[0019] This utility model description introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0031] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0032] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0033] This utility model provides a fan housing assembly. The fan housing assembly provided by this utility model can be applied to range hoods. The following will describe in detail a fan housing assembly according to an embodiment of this utility model with reference to the accompanying drawings.

[0034] See also Figures 1a to 6The air handling unit 10 may include a cabinet 110 and a germicidal lamp assembly 120. The cabinet 110 may be enclosed to form a receiving cavity 111. The germicidal lamp assembly 120 may be connected to the cabinet 110. The cabinet 110 may have an inner wall surface 112. The light emitted by the germicidal lamp assembly 120 may at least partially be directed toward the inner wall surface 112. A reflective structure 130 may be provided on at least a portion of the inner wall surface 112. The reflective structure 130 may be configured to reflect the light incident on the inner wall surface 112.

[0035] The air handling unit 10 of this utility model has a reflective structure 130 on its inner wall surface 112. The light emitted by the germicidal lamp assembly 120 can be reflected by the reflective structure 130, and the reflected light can sterilize the components located in the accommodating cavity 111. This not only improves the light reflection efficiency and eliminates irradiation dead angles, but also ensures the sterilization effect. It also reduces the dependence on the number and power of the lamps in the germicidal lamp assembly 120, and extends the service life of the germicidal lamp assembly 120. At the same time, the structure is simple and reduces energy consumption and maintenance costs.

[0036] In some embodiments, the lamp tube in the germicidal lamp assembly 120 can be an ultraviolet lamp. Ultraviolet lamps emit ultraviolet light. Ultraviolet light can achieve a highly efficient and rapid broad-spectrum sterilization effect against pathogens such as bacteria and viruses, typically achieving inactivation within seconds. Furthermore, using ultraviolet lamps for sterilization does not leave chemical residues on the air handling unit 10, making it more environmentally friendly and safer, posing no harm to human health, and not affecting the kitchen environment.

[0037] See also Figure 1b , Figure 2 , Figure 5 and Figure 6 A fan assembly 20 can be disposed within the accommodating cavity 111. Light reflected by the reflecting structure 130 can have a reflection path. The fan assembly 20 can be located on the reflection path. Thus, the light reflected by the reflecting structure 130 can sterilize the fan assembly 20. Understandably, Figure 1b , Figure 2 , Figure 5 and Figure 6 The arrow shown indicates the reflection path of the light rays reflected by the reflective structure 130.

[0038] Understandably, when the fan assembly 10 is applied to the range hood 1, the germicidal lamp assembly 120 can be activated when the range hood 1 is in standby mode. At this time, the light emitted by the germicidal lamp assembly 120 can sterilize the components and air in the accommodating cavity 111. Alternatively, the germicidal lamp assembly 120 can be activated when the range hood 1 is in operation. At this time, the light emitted by the germicidal lamp assembly 120 can sterilize the components and the fumes drawn into the accommodating cavity 111, thereby reducing the pollution to the outdoor environment when the fumes are discharged outdoors.

[0039] See again Figure 1b , Figure 2 , Figure 5 and Figure 6 The fan assembly 20 may have a volute 210. The volute 210 may have an air inlet 211. The inner wall surface 112 may have a opposing wall surface 1121 opposite to the air inlet 211. A reflective structure 130 may be disposed on the opposing wall surface 1121. In this way, the light reflected by the reflective structure 130 can pass through the air inlet 211 to sterilize the interior of the volute 210 and the components inside the volute 210, further eliminating blind spots in irradiation.

[0040] Specifically, the fan assembly 20 may also include a motor 220 and an impeller 230. The motor 220 and impeller 230 are disposed inside the volute 210 via an air inlet 211. The motor 220 drives the impeller 230 to rotate at high speed, creating a negative pressure area near the air inlet 211, thereby drawing oil fumes into the volute 210 and then expelling them outdoors. By providing a reflective structure 130 on the opposing wall surface 1121, the light reflected by the reflective structure 130 can sterilize the motor 220 and impeller 230 through the air inlet 211, thereby improving the service life of the motor 220 and impeller 230.

[0041] See also Figure 1b , Figure 2 , Figure 4 , Figure 5 and Figure 6The cabinet 110 may have a top panel 113 and side panels. A germicidal lamp assembly 120 may be mounted on the top panel 113. A reflective structure 130 may be mounted on the inner wall surface 112 of the side panel. Thus, with the germicidal lamp assembly 120 mounted on the top panel 113, light shines downwards. When the light shines onto the inner wall surface 112, the reflective structure 130 can reflect the light to the fan assembly 20 to a great extent, thereby sterilizing the fan assembly 20, eliminating blind spots, and improving light utilization. Understandably, a portion of the light emitted by the germicidal lamp assembly 120 can directly shine onto the fan assembly 20 for direct sterilization, while another portion can shine onto the inner wall surface 112 and then be reflected back to the fan assembly 20, improving light utilization and ensuring the sterilization effect of the germicidal lamp assembly 120 on the fan assembly 20.

[0042] In some embodiments, in conjunction with reference Figure 1b , Figure 2 , Figure 4 , Figure 5 and Figure 6 The top plate 113 has clearance holes 1131 that can accommodate the size of the germicidal lamp assembly 120. The germicidal lamp assembly 120 can be installed on the top plate 113 from top to bottom, partially abutting against the top plate 113. The part of the germicidal lamp assembly 120 that abuts against the top plate 113 can be locked to the top plate 113 by fasteners (not shown in the figure). This facilitates the installation and fixation of the germicidal lamp assembly 120 and effectively ensures that the light emitted by the germicidal lamp assembly 120 can illuminate the receiving cavity 111. Specifically, the fasteners can be screws, bolts, etc. After prolonged use, oil stains may adhere to the surface of the germicidal lamp assembly 120, affecting its sterilization effect and service life. In this case, the fasteners can be removed to detach the germicidal lamp assembly 120 from the top plate 113 for cleaning. Of course, the germicidal lamp assembly 120 can also be mounted on the top plate 113 by snap-fit, adhesive, welding, or other methods.

[0043] See also Figure 1a , Figure 1b , Figure 2 , Figure 4 , Figure 5 and Figure 6 The side panels may include a front side panel 1141, a rear side panel 1142, a left side panel 1143, and a right side panel 1144. A reflective structure 130 may be provided on the inner wall surface 112 of at least one of the front side panel 1141, rear side panel 1142, left side panel 1143, and right side panel 1144. This improves light reflection efficiency, eliminates blind spots, increases light utilization, and simultaneously simplifies the structure and reduces maintenance costs.

[0044] It should be noted that the front side panel 1141, rear side panel 1142, left side panel 1143, and right side panel 1144 are named according to their position relative to the operator. When using the air handling unit 10, the operator usually faces the air handling unit 10. In the forward-backward direction of the operator, the side panel relatively closer to the operator is the front side panel 1141, and the side panel relatively farther from the operator is the rear side panel 1142. In the left-right direction of the operator, the side panel located to the left of the operator is the left side panel 1143, and the side panel located to the right of the operator is the right side panel 1144.

[0045] In an embodiment not shown, a reflective structure 130 may be provided on the inner wall surface 112 of one of the front side panel 1141, rear side panel 1142, left side panel 1143, and right side panel 1144. Preferably, the reflective structure 130 may be provided on the side panel opposite to the air inlet 211 of the volute 210. In this way, the light reflected by the reflective structure 130 can sterilize the interior of the volute 210 and the components inside the volute 210 through the air inlet 211, further eliminating blind spots in illumination.

[0046] Understandably, in this utility model, in conjunction with reference to Figure 1b , Figure 2 , Figure 3 , Figure 5 and Figure 6 The side plate opposite to the air inlet 211 of the volute 210 is the rear side plate 1142. The inner wall surface 112 on the rear side plate 1142 can form the opposing wall surface 1121.

[0047] In an embodiment not shown, a reflective structure 130 may be provided on the inner wall surface 112 of any two of the front side plate 1141, rear side plate 1142, left side plate 1143, and right side plate 1144. Preferably, the reflective structure 130 may be provided on the rear side plate 1142 and any of the other side plates. In this way, the light reflected by the reflective structure 130 can sterilize the interior of the volute 210 and the components inside the volute 210 through the air inlet 211, further eliminating blind spots in irradiation. In one embodiment of this utility model, the reflective structure 130 may be provided on the rear side plate 1142 and the front side plate 1141. In this case, it is effectively ensured that the light emitted by the germicidal lamp assembly 120 can irradiate the fan assembly 20 after reflection.

[0048] In an embodiment not shown, reflective structures 130 may be provided on the inner wall surfaces 112 of three of the following: front side panel 1141, rear side panel 1142, left side panel 1143, and right side panel 1144. Preferably, the reflective structure 130 may be provided on the rear side panel 1142 and any of the other two side panels. Thus, the light reflected by the reflective structure 130 can sterilize the interior of the volute 210 and its components through the air inlet 211, further eliminating blind spots in illumination.

[0049] Refer to Figures 1 to 2 Figure 6 Reflective structures 130 can be provided on the inner wall surfaces 112 of the front side panel 1141, rear side panel 1142, left side panel 1143, and right side panel 1144. In this case, the reflective structure 130 can reflect the light emitted by the germicidal lamp assembly 120 multiple times, effectively ensuring the reflection efficiency and sterilization effect, and effectively eliminating irradiation dead angles.

[0050] See again Figures 1b to 6 An uneven structure can be formed on the inner wall surface 112 by pressing. This uneven structure can form a reflective structure 130. In this way, the uneven structure not only increases the reflective area, allowing the germicidal lamp assembly 120 to achieve sterilization even when operating at lower power, but also reflects the light irradiated onto the inner wall surface 112 in different directions, making full use of every beam of light emitted by the germicidal lamp assembly 120, eliminating blind spots, improving light utilization, and facilitating the fabrication of the reflective structure 130, thus reducing maintenance costs.

[0051] In some embodiments, in conjunction with reference Figures 1b to 6 The uneven structure can be prism-shaped. In this way, the uneven structure can reflect the light that shines on the inner wall surface 112 in different directions, making full use of every beam of light emitted by the germicidal lamp assembly 120 and eliminating blind spots in the illumination.

[0052] For example, the uneven structure can be in the shape of a triangular prism. Specifically, see [link to relevant documentation]. Figure 3 The uneven structure can have a base 132 and a vertex 134. The two side edges 133 can be inclined relative to the inner wall surface 112 and connected between the base 132 and the vertex 134, so that the uneven structure forms a triangular slope-like shape. The plane formed by the base 132 and the two side edges 133 can be a reflective surface 131.

[0053] For example, the uneven structure can be in the shape of a quadrilateral prism. Understandably, two triangular prism-shaped uneven structures can be joined side-to-side to form a quadrilateral prism-shaped uneven structure.

[0054] In some embodiments, see Figure 5 The uneven structure can have a parabolic reflective surface 131. In this way, the uneven structure can reflect and focus light, enhancing the sterilization effect of the reflected light. Specifically, the light can be focused onto the air inlet 211 of the volute 210, thereby effectively sterilizing the interior of the volute 210, as well as the motor 220 and impeller 230.

[0055] In some embodiments, see Figure 6The uneven structure can have an elliptical reflective surface 131. In this way, the uneven structure can reflect and focus light, enhancing the sterilization effect of the reflected light. Specifically, the light can be focused onto the air inlet 211 of the volute 210, thereby effectively sterilizing the interior of the volute 210, as well as the motor 220 and impeller 230.

[0056] In embodiments not shown, the uneven structure may take on other shapes that can improve light reflection efficiency.

[0057] In an embodiment not shown, the inner wall surface 112 may have an uneven structure provided by means of adhesive, snap-fit, welding, etc. The uneven structure can form a reflective structure 130.

[0058] In some embodiments, a reflective film layer may be provided on the inner wall surface 112. The reflective film layer can form a reflective structure 130. In this way, the light reflection efficiency is effectively improved, dead angles of irradiation are eliminated, and the sterilization effect is guaranteed. The dependence on the number and power of lamps in the germicidal lamp assembly 120 is reduced, and the service life of the germicidal lamp assembly 120 is extended.

[0059] In some embodiments, a reflective film layer and a reflective structure 130 may be simultaneously provided on the inner wall surface 112. This further ensures the reflectivity and sterilization effect.

[0060] For example, reflective film layers can be simultaneously provided on the inner wall surface 112 and the reflective surface 131 of the reflective structure 130. In this way, both reflection efficiency and sterilization efficiency are effectively guaranteed.

[0061] For example, the reflective film layer may be provided only on the reflective surface 131 of the reflective structure 130. This reduces manufacturing costs while ensuring both reflection efficiency and sterilization efficiency.

[0062] For example, a reflective film layer may be provided only on the inner wall surface 112 where the reflective structure 130 is not formed by compression molding or on the inner wall surface 112 where the reflective structure 130 is not provided. In this way, both reflection efficiency and sterilization efficiency are guaranteed.

[0063] Specifically, the reflective film can be at least one of an aluminum film, a mirror film, or a silica coating. This effectively ensures the light reflection efficiency. Understandably, aluminum and mirror films can improve light reflection efficiency, while the silica coating can increase the roughness and reflective area of ​​the inner wall surface 112, thereby improving light reflection efficiency. Of course, the reflective film can also be made of other materials that can improve light reflection efficiency.

[0064] According to another aspect of the present invention, a range hood 1 is provided, including a smoke collection assembly 30 and a fan assembly 10 as described above. Figure 1a and Figure 1b As shown, the smoke collection assembly 30 can be connected to the lower part of the fan housing assembly 10. Since the fan housing assembly 10 described above has the aforementioned beneficial effects, the range hood 1 including the fan housing assembly 10 described above also has the aforementioned beneficial effects, which will not be elaborated further here.

They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0066] For ease of description, relative terms such as "above," "over," "on the upper surface of," and "above" are used here to describe the regional positional relationship of one or more components or features shown in the figures to other components or features. It should be understood that relative terms include not only the orientation of the component as depicted in the figure but also different orientations during use or operation. For example, if the components in the figures are inverted as a whole, "above" or "above other components or features" will include cases where the component is "below" or "under" other components or features. Thus, the exemplary term "above" can include both "above" and "below." Furthermore, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and this document intends to include all such cases.

[0067] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in sequences other than those illustrated or described herein.

[0069] This utility model has been described through the above embodiments. However, it should be understood that the above embodiments are for illustrative purposes only and are not intended to limit the utility model to the described embodiments.
